Plural predication is a pervasive part of ordinary language. We can say that some people are fifty in number, are surrounding a building, come from many countries, and are classmates. These predicates can be true of some people without being true of any one of them; they are non-distributive predications. However, the apparatus of modern logic does not allow a place for them. Thomas McKay here explores the enrichment of logic with non-distributive plural predication and quantification. His book will be (...) of great interest to philosophers of language, linguists, metaphysicians, and logicians. (shrink)

Frege's theory of indirect contexts and the shift of sense and reference in these contexts has puzzled many. What can the hierarchy of indirect senses, doubly indirect senses, and so on, be? Donald Davidson gave a well-known 'unlearnability' argument against Frege's theory. The present paper argues that the key to Frege's theory lies in the fact that whenever a reference is specified (even though many senses determine a single reference), it is specified in a particular way, so that giving a (...) reference implies giving a sense; and that one must be 'acquainted' with the sense. It is argued that an indirect sense must be 'immediately revelatory' of its reference. General principles for Frege's doctrine of sense and reference are sated, for both direct and indirect quotation, to be understood iteratively. I also discuss Frege's doctrine of tensed and first person statements in the light of my analysis. The views of various other authors are examined. The conclusion is to ascribe to Frege an implicit doctrine of acquaintance similar to that of Russell. (shrink)

It is a characteristically Fregean thesis that the sense expressed by an expression is the linguistic meaning of that expression. Sense can play this role for Frege since it meets fundamental desiderata for meaning, that it be universal and invariantly expressed and objectively the same for everyone who knows the language. It has been argued,1 however, that, as a general thesis about natural languages, the identi cation of sense and meaning cannot be sustained since it is in con ict with (...) another characteristically Fregean thesis, that sense uniquely determines reference. The argument is quite simple and can be outlined as follows. Assume the two theses we have just stated. (shrink)

My concern here is to motivate some theses in the philosophy of mind concerning the interpersonal character of intentions. I will do so by investigating aspects of shared agency. The main point will be that when acting together with others one must be able to act directly on the intention of another or others in a way that is relevantly similar to the manner in which an agent acts on his or her own intentions. What exactly this means will become (...) clearer once we understand what it is to act directly on one’s own intentions. But I take it to be a fundamental assumption of the prevailing individualism of the theory of action— one at the core of its conception of the separateness of individuals— that one person cannot act directly on another’s intention. I agree that there is an important way in which we are or can be separate and autonomous thinkers and agents. But the way the individualist tries to capture this separateness is misguided. (shrink)

Demonstratives seem to have posed a severe difficulty for Frege’s philosophy of language, to which his doctrine of incommunicable senses was a reaction. In “The Thought,” Frege briefly discusses sentences containing such demonstratives as “today,” “here,” and “yesterday,” and then turns to certain questions that he says are raised by the occurrence of “I” in sentences (T, 24-26). He is led to say that, when one thinks about oneself, one grasps thoughts that others cannot grasp, that cannot be communicated. However, (...) nothing could be more out of the spirit of Frege’s account of sense and thought than an incommunicable, private thought. In the first part of the paper, I explain the problem demonstratives pose for Frege, and explore three ways he might have dealt with it. I argue that none of these ways provides Frege with a solution to his problem consistent with his philosophy of language. The first two are plausible as solutions, but contradict his identification of the sense expressed by a sentence with a thought. The third preserves the identification, but is implausible. In the second part, I suggest that Frege was led to his doctrine of incommunicable senses as a result of some appreciation of the difficulties his account of demonstratives faces, for these come quickly to the surface when we think about “I.” I argue that incommunicable senses won’t help. I end by trying to identify the central problem with Frege’s approach, and sketching an alternative. (shrink)

Frege held that referring expressions in general, and demonstratives and indexicals in particular, contribute more than just their reference to what is expressed by utterances of sentences containing them. Heck first attempts to get clear about what the essence of the Fregean view is, arguing that it rests upon a certain conception of linguistic communication that is ultimately indefensible. On the other hand, however, he argues that understanding a demonstrative (or indexical) utterance requires one to think of the object denoted (...) in an appropriate way. This fact makes it difficult to reconcile the view that referring expressions are "directly referential" with any view that seeks (as Grice's does) to ground meaning in facts about communication.

This paper offers an analysis of the logical form of plural action sentences that shows that collective actions so ascribed are a matter of all members of a group contributing to bringing some event about. It then uses this as the basis for a reductive account of the content of we-intentions according to which what distinguishes we-intentions from I-intentions is that we-intentions are directed about bringing it about that members of a group act in accordance with a shared plan.

Perry argues that certain sorts of indexicals are 'essential', in the sense that they cannot be eliminated in favor of descriptions. This paper also introduces the influential idea that certain sorts of indexicals play a special role in thought, and have a special connection to action.

A long-standing theme in discussion of perception and thought has been that our primary cognitive contact with individual objects and events in the world derives from our perceptual contact with them. When I look at a duck in front of me, I am not merely presented with the fact that there is at least one duck in the area, rather I seem to be presented withthisthing (as one might put it from my perspective) in front of me, which looks to (...) me to be a duck. Furthermore, such a perception would seem to put me in a position not merely to make the existential judgment that there is some duck or other present, but rather to make a singular, demonstrative judgment, that that is a duck. My grounds for an existential judgment in this case derives from my apprehension of the demonstrative thought and not vice versa. (shrink)

Frege’s distinction between sense (Sinn) and meaning (Bedeutung) is his most influential contribution to philosophy, however central it was to his own projects, and however he may have conceived its importance. Philosophers of language influenced by, or reacting against the distinction, and historians of philosophy commenting on it, have all contributed to the voluminous literature surrounding it.1 Nonetheless in this essay I hope to shed new light on the distinction by considering it in the context of the development of Frege’s (...) thought, and connecting it more intimately than is usually done with Frege’s interests in logic, especially his views on judgment, truth and inference, which were central to his own projects as he conceived them.

This paper focuses on two enduring features of Gareth Evans’s work. The first is his rethinking of standard ways of understanding the Fregean notion of sense and the second his sustained attempt to undercut the standard opposition between Russellian and Fregean approaches to understanding thought and language.I explore the peculiar difficulties that ‘I’ poses for a Fregean theory and show how Evans’s account of the sense of the first person pronoun can be modified to meet those difficulties.

I want to reflect on some functions of memory and their relations to traditional issues about personal identity. I try to elicit ways in which having memory, with its presupposition of agent identity over time, is integral to being a person, indeed to having a representational mind.

This paper takes up David Kaplan's suggestion that the phenomenon of cognitive dynamics can be approached via a study of what it takes for someone to change her mind. It is argued that in order for a subject to be able to change her mind about something, there must be occasions on which the following is the case: (1) First, the subject believed of an 'x' that it was f, now she believes of 'x' that it is not-f. (2) She (...) stopped believing of 'x' that it was f before she started believing of 'x' that it was not-f. (3) She knows that (1) and (2). The first part of the investigation shows why (1) - (3) are necessary within an account of what it is for someone to change her mind. The second part focuses on condition (3) and argues that it entails that the sameness or difference of thought content over time must sometimes be an epistemic given, i.e., that the subject can know that a thought she entertains now is the same as a thought she entertained earlier.

It is sometimes said that ordinary linguistic exchange, in ordinary conversation, is a matter of securing and sustaining joint attention. The minimal condition for the success of the conversation is that the participants should be attending to the same things. So the psychologist Michael Tomasello writes, ‘I take it as axiomatic that when humans use language to communicate referentially they are attempting to manipulate the attention of another person or persons.’ I think that this is an extremely fertile approach to (...) philosophical problems about meaning and reference, and in this paper I want to apply it to the case of the first person. So I want to look at the case in which you tell me something about yourself, using the first person, and we achieve joint attention to the same object. But I begin with some remarks about how this approach applies to proper names and to perceptual demonstratives. (shrink)

The topic of this book is self-consciousness, which is a kind of knowledge, namely knowledge of oneself as oneself, or self-knowledge.

In this paper, I argue against an influential view of Frege's writings on indexical and other context-sensitive expressions, and in favour of an alternative. The centrepiece of the influential view, due to (among others) Evans and McDowell, is that according to Frege, context-sensitiveword-meaning plus context combine to express senses which are essentially first person, essentially present tense and so on, depending on the context-sensitive expression in question. Frege's treatment of indexicals thus fits smoothly with his Intuitive Criterion of difference of (...) sense. On my view, by contrast, Frege stuck by the view which he held in his unpublished 1897 ‘Logic’, namely that the senses expressed by the combination of context-sensitive word-meaning and context could just as well be expressed by means of non-context-sensitive expressions: being first person, present tense and so on are properties, in Frege's view, only of language, not of thought. Given the irreducibility of indexicals – a phenomenon noticed by Castañeda, Perry and others – Frege's treatment of indexicals thus turns out to be inconsistent with the Intuitive Criterion. I argue that Frege was not aware of the inconsistency because he was not aware of the irreducibility of indexicals. This oversight was possible because the source of Frege's interest in indexicals, as inother context-sensitive expressions, differed from that of contemporary theorists. Whereas contemporary theorists are most often interested in indexicals (and in Frege's treatment of them) because they are interested in the indexical versions of Frege's Puzzle and their relation to psychological explanation, Frege himself was interested in them because they pose a prima facie threat to his general conception of thoughts. The only indexical expression Frege's view of which the above account does not cover is ‘I’ insofar as it is associated with ‘special and primitive’ senses, but Frege did not introduce such senses with a view to explaining theirreducibility of ‘I’ his real reason for introducing them remains obscure.
